BIS Certification for High Strength Reformed Steel Bars IS 1786

Steel bars look simple, but they build the strong base of homes, offices, bridges, and towers. If one steel bar breaks, a building can fall. That’s why using the right type of steel, and proving its quality, is not just a choice—it is a rule. In India, when steel bars are used in concrete, they must match a set standard. That standard is called IS 1786. BIS is the authority behind it.

BIS gives a license to steel makers. That license is called ISI certification. For High Strength Deformed Steel Bars and Wires, this certification proves the steel is safe, strong, and built to last. Without it, the bars cannot be sold or used legally for big projects. The license ensures that every bar has passed strict tests for strength, bend, and size.

Getting this certification may look hard. But once you know the steps, the process becomes clear. In this article, we explain all the details regarding BIS certification for IS 1786

What is IS 1786?

IS 1786 is the Indian Standard that manages High Strength Deformed Steel Bars and Wires for Concrete Reinforcement. These bars are also called TMT bars or rebar. The standard was first published by the Bureau of Indian Standards (BIS) in 1985 and has been updated with time to meet new safety needs.

What is BIS Certification for IS 1786?

BIS certification means the product is made under BIS rules and it passes BIS checks. For IS 1786, the product is high-strength reformed steel bars and wires.

If you want to sell these bars in India, you must get the ISI mark from BIS. This is mandatory under the Quality Control Order (QCO) issued by the Government of India. Without this mark, selling, storing, or using the bars is a violation of law.

Who Must Get BIS Certification for IS 1786?

You must apply for this license if you are:

  • A high-strength deformed wires or steel bars manufacturer  
  • An importer who brings steel bars into India for sale
  • A contractor using non-certified steel in government or public projects

It applies to:

  • Indian factories making steel bars
  • Foreign firms who want to sell in India (through a foreign manufacturer certification scheme)

You cannot skip this if you work in the steel business. It’s not just about following law—it’s about protecting life and property.

If your system matches BIS rules, the officer collects samples for lab testing.

The sample is tested in the BIS-recognized lab. It must pass all the mechanical and chemical property tests given in IS 1786.

Tests include:

  • Yield stress
  • Ultimate tensile strength

Step 6: Grant of License
